The MC33464 series are micropower undervoltage sensing circuits that
are specifically designed for use with battery powered microprocessor based
systems, where extended battery life is required. A choice of several
threshold voltages from 0.9 V to 4.5 V are available. These devices feature a
very low quiescent bias current of 0.8 µA typical.

The MC33464 series features a highly accurate voltage reference, a
comparator with precise thresholds and built–in hysteresis to prevent erratic
reset operation, a choice of output configurations between open drain or
complementary MOS, and guaranteed operation below 1.0 V with extremely
low standby current. These devices are available in either SOT–89 3–pin or
SOT–23 5–pin surface mount packages.

Applications include direct monitoring of the MPU/logic power supply
used in portable, appliance, automotive and industrial equipment.

MC33464 Features:

• Extremely Low Standby Current of 0.8 µA at V

• Wide Input Voltage Range (0.7 V to 10 V)

• Monitors Power Supply Voltages from 1.1 V to 5.0 V

• High Accuracy Detector Threshold (±2.5%)

• Two Reset Output Types (Open Drain or Complementary Drive)

• Two Surface Mount Packages (SOT–89 or SOT–23 5–Pin)

Propagation Delay Time (Note 2)

NOTES: 1. Low duty pulse techniques are used during test to maintain junction temperature as close to ambient as possible.

2.Propagation delay time is measured from the rising or falling edge of the input voltage to the point where the output voltage has transitioned to 50%
of its final value.
